I ran across a Weed Science Society of America (WSSA) press release from last summer that I found interesting.
The article, entitled "The Deadly Problem of Poisonous Weeds", outlines ten poisonous weeds in North America that are particularly dangerous and features information from UC Davis Cooperative Extension Weed Specialist Joe DiTomaso.
The article includes basic information on the toxicity, identification, and links to photos of::
1. Poison hemlock
2. Waterhemlocks
3. Oleander
4. Bittersweet nightshade
5. Common pokeweed or pokeberry
6. Pennyroyal
7. Meadow deathcamas
8. Foxglove
9. Groundcherry
10. Jimsonweed
The article can be accessed here: http://www.prweb.com/releases/2010/07/prweb4298154.htm and I have also attached a pdf at the bottom of this post.
Take care (and don't eat poisonous weeds!),
Brad
